SPECIFICATION formingpart of Letters Patent No. 255,656, dated March 28,1882,

Application filed February 8,1882. (No model.)

To all whom it may concern:

I Be it known that I, JACOB NIXON, of Winfield, in the county of Cowleyand State of Kansas, have invented certain new and useful Improvementsin Lifting-Jacks; and Ido hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it pertains to make and use the same.

My invention relates to lifting-jacks, the object being to provide ajackfor use with vehicles which will be of such construction as to avoid theuse of stepped bars or ratchets, and the expense incident to the use ofsuch features of construction, and to provide a jack of few parts,adapted to be easily operated and not liable to breakage ordisarrangement.

The invention consists in the combinations of parts hereinafter setforth, and pointed out in the claims.

In the drawings, Figure 1 is-a side elevation of my improved jack. Fig.2 is a front view of the same, and Figs. 3 and 4represent parts indetail.

A represents the main standard of thejack. It is cut away or recessed toform a step, a, which latter is slotted, as shown at a, to receive atongue, I), ofa bearing'block, B. The tongue 6 is held pivotally withinthe slotof the standard A by apin, b, on which the block B is adapted toturn.

C represents the operating-lever of the jack, provided at its inner endwith a metallic loop or staple, D, which fits over the upper end of thestandard A, and is pivoted thereto by a pivot, 61. The ends of the loopare rigidly secured on either side of the inner end of the lever 0, andthe pivot cl forms the fulcrum of the lever.

E represents the axle-bearing standard or block, formed with the curvedeud bearing, e, for the axle, and with a cut-away or recessed portion,e,which adapts the standard to the recess of the standard A. At itslower end the standard E is provided with a guide, F, formed of ametallic strip bent around the standard A, and having its ends securedto the standard E by a pivot, f. A connecting-rod, G, is secured at oneend near the outer end of the operating-lever C, while its opposite endis bifurcated and secured to lugs or pins 9, projectaxle it is turned tothe position shown in the full lines of Fig.1-that is, at an angle tothe standard A-when by depressing the lever G the standard E is forcedto a vertical position, (dotted lines, Fig. 1,) and theaxle is raisedand the jack locked in raised position.

It will be apparent that my improvement is simple both in itsconstruction and operation, and is, moreover, of an inexpensive anddurable form.

Having fully described my invention, what I claim'as new, and desire tosecure by Letters Patent, is

1. In a lifting-jack, the combination, with a recessed main standard, ofan axle-bearing standard connected to said main standard by a pivot andloop-guide, an operating-lever provided with a metallic loop pivoted tothe main standard, and a connectingrod secured at one end to theoperating-le\-'er and at its opposite end to the axle-bearingstandard,substantially as set forth.

2. In a lifting-jack, the combination, with a standard provided with aslotted step, of a bearing-block pivoted to the standard and adapted torest on said step or beturned away from the latter, substantially as setforth.

3. The combination, with the recessed standard A,havin g the slottedstep a, of the pivoted block 13, the recessed standard E, connected tothe standard A by the loop-guide F and pivot f, the operating-lever 0,connected to the standard A by the metallic loop D and pivot d, and theconnecting-rod G, substantially as set forth.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.

JACOB NIXON. Witnesses: W. P. HACKNEY, L. D. ZENoR.
